There are tricks that can be done to imitate multiple collisions from the same source on multiple targets, but that involves duplicating the source figure.
For example, say you want your G8M (not Dicktator) to touch both G8F and GP, then you need 2 G8Ms and 1 G8F with 1 GP, posed the exact same way, then :
Set G8F to collide with G8M1 (G8M1 deforms G8F).
Set GP to collide with G8M2 and hide G8M2 (G8M2 deforms GP even when invisible) .
For this, Dicktator does not interact. And only one render is needed.
Now if you want multiple sources to collide with multiple targets (Dicktator also colliding), that involves either duplicating both the source and target, or changing the collisions between the renders, and there will be some post-work involved.
For example, G8M touching both G8F And GP while Dicktator touches both G8F And GP, for that you need 2 G8Ms + 2 Dicktators and 2 G8Fs with 2 GPs, posed the exact same way, then :
Set G8F1 to collide with G8M1.
Set GP1 to collide with G8M2 and hide G8M2.
Set GP2 to collide with Dicktator1.
Set G8F2 to collide with Dicktator2 and hide Dicktator2.
Render once with G8F1+GP1 visible/G8F2+GP2 invisible, and again with G8F1+GP1 invisible/G8F2+GP2visible, and do some post work in photoshop or gimp to merge the results (spot render helps with this case).
Changing the collisions between renders is also possible if you want to use just one of each figure as well, but you get the idea, it involves either that, or multiple figures posed the same way, and multiple renders, then post-work to merge the renders into one image, tedious sadly for that one.
