Strymon expression/favorite switch wiring question

[bartdude]

Hi,
A noob and a first time poster here. I'm planning on putting together an expression pedal for my Strymon Brigadier Delay. I came upon this simple schematic:



Now, I have this idea of having the 'favorite switch' (pic below) and the expression pedal selectable with a toggle switch. I'm pretty sure that these two functions cannot be on at the same time and need to be assigned individually, so I'd like to add a toggle switch that'll select between the 2 functions. So, pretty much it's an expression pedal and a favorite switch to a selector switch to a single jack output. Would that be possible? Thanks for any assistance in advance.
