How to hit double slide notes in the same direction using joy2key

Im trying to emulate the ps4 controls using joy2key, and most of it is going well. However, im having a problem, hitting double slide notes that go in the same direction, for example this: http://prntscr.com/k0v65o

I can hit pretty much every other note or combination of notes, including when the slide notes go in the opposite direction such as one left, one right, but when i try to hit notes like in the pic, it only registers one slide note, even if i have 2 buttons mapped to the same slide note. is there some way around this to where if i push left/right on both the analogs (using joy2key) itll register as a double left press? Or maybe someone can make a mod that allows this feature


On a side note, is it possible to where R1 and L1 can be a macro for quads using joy2key? (or someone can make a mod that allows this feature, although ive seen quite a few requests for macros

Set your left analog as your keyboard's left and right slider keys for PPD
Set your right analog as your keyboard's Square/Circle keys (if you're using CSInput, if not set as Triangle/Circle)
