Relay Bypass with "latch" function

[Coda-effects]

Hello !

Do you know if there are any relay bypass PCB out there with a "latch / unlatch" function ?
I mean the possibility to wire a switch that would let you choose between normal switching or a temporary switching while your foot is on the switch.

I am currently designing a tremolo, and I think it could be a nice feature to add to it (especially with square waves)
I am also learning PIC programming, but relay bypass is not as easy as it seems to program...

Thank you !

OK, so I finally decided to code a PIC (12F675) to make it myself.

It has been quite a journey, but it should be working soon (just waiting for parts...).I used an external switch to set whether you want a "momentary" activation or not.
If that is of any interest for someone, I can post the code
