[feature request] output combinatorial results

[rjgoif]

if I have the prompt {A | B} with {C | D}, I know I need to iterate 2 x 2 = 4 times to get the combinatorial complete result.

But if I have wildcards, I have no idea how many iterations are needed without going into each txt file (and there can be many!) and counting the entries, then doing the math.

It would be nice to either a) have a loop node that totals the combinatorial requirements for a prompt and queues that many to be processed or b) at least a string output/dynamic field somewhere that tells me what the combinatorial result would be.

In the A1111 implimentation, option A is done automatically when "combinatorial mode" is checked, so every iteration is done with a click of a button.

This would be helpful. In A1111 there's a checkbox to iterate through all options. I have to do the math every time I want to iterate in ComfyUI.
