'dual mode' pedal board; ideas?

Hi-

Im wondering if anyone has a nice solution to the following issue:

I like using my pedalboard with the time based effects (delay, chorus, vibe, and looper) in the effects loop and with the gain and filter stuff in front.
however, I often find myself having to plug into back line at festivals etc. where I cant easily do a 'four cable' setup.

With a patch panel (normal) at home I've been able to set up my pedals so that by default the entire 'time' loop is appended to the 'gain' loop but if I patch an additional 2 cables in (amp effects send and return) it takes the time stuff out of the 'front'. But a 48 port patch bay is not something Im adding to
my pedal board!

Has anyone used a widget that is effective for this? If not, I might take a shot at making one. I think a very small form factor 4 port patch bay would do it. no external switched or anything would be needed.

I know I could just separate the board into two but I like to keep the board wired nice and tight both for quick setup and so that I don't get
cable continuity problems from stuff flexing.

ideas?

I'm putting together a board with a similar requirement for combining the pre/post FX into a "front of amp" pedal board. I've preordered a Temple Audio pedal board that will come with a patch bay on the side to route the cables to the amp FX loop so I plan on just using a short jumper cable on the patch bay to put it in "front of amp" mode.

You could wire this yourself if you are handy too. There are also patch boxes that will achieve the same type of thing:
