How to use an Expression Pedal Input as as IA Switch?

[Hugomack]

I only use two Expression Pedals (one for Wah/Whammy, and the other for speeds for Vibe and PanTrem, and feedback for delays...) but would like more Switches.

I'm using one Expression Pedal input as a momentary switch for the Tuner (so I can make on-off noises...).

But I'd like to use my remaining expression pedal input as an IA switch - requiring it to be Toggle and not momentary, which is as far as I can get it to go. So, now I can turn on the required effect, but only so long as I hold down the switch...

Any ideas please, on how I could get the Exp input to keep itself turned on until the switch is pressed again?

You'd have to use a latching switch.

Boss FS6 again I guess... The Swiss Army knife of switches...

Set the mode switch(es) on the FS-6 to ''latch"
