Possible to send signal to wall switch when Shelly 2.5 gets an instruction?

Good morning,

I'm installing some Shelly 2.5 behind my wall switches to operate my roller/shutters.. they work fine when I wire them up as shown in the manual..

Problem is: in one room I have 2 roller/shutters that are not connected to each other (seperate cable to each of them) that are controlled by a single switch.. So when I install the Shelly I need 5 WAGO's (they call those that here, don't know how they are called in english, basically it allows for multiple wires to come in and out to a single point) for Neutral, Line, Ground, Output 1 and Output 2 and I just can't get them behind the switch..just not enough room..

So I tried wiring them up so I forgo the Wago for both outputs and plug 1 wire into the socket and 1 into output port, and then the other wire from the socket goes into the Switch port of the Shelly.. but now when I just the wall switch they work, but when I want to use them remotely, only 1 motor works because the shelly doesn't talk to the switch to say "hey, you need to lower the other one too".. Is there a way to get around this without running extra wires (I can't get to the motors themselves, they are walled in)

Hope the images made it somewhat clear

I realized my images where not clear at all (thx caravanboy) so I tried to rework the diagrams to make it more understandable.. I'm still new to this

this is how shelly should be wired (left out all the standard wiring):

I was wondering if it would be possible (probably in the way of software/firmware update).. to get the SW ports on the shelly to send a signal back to the switch so the other port on the wall switch gets the signal (current) to open/close the blinds.
This way I can leave 2 WAGO's out and I can fit everything inside the wall box..

For example:

I use the wall switch button "UP":

- signal/current goes from the first port to the Shelly SW1, which triggers O1 so motor 1 goes up. Motor 2 is triggered directly from the other port on the switch.. no problem

When using the Shelly App:

- SW1 is triggered, so O1 makes motor 1 go up.. but Motor2 doesn't get a signal at all.. Would it be possible to have SW1 give signal/current back to wall switch? Or only possible in one-way direction due to hardware constraint?

caravanboy : Thank you for taking the time to reply, however I'm already using the 221 versions, but I have 3 5-ports for ground, neutral and live wires and those 2 3-ports are just to much .. I've looked into using ferrules but don't think those would work..
