I am slightly confused by your first proposed solution. Essentially, my problem stems from the fact that I would prefer "to assign a subject ID after the screening", to put it simply, even though I know this is illogical. The only reason I need to do this, however, is because (as far as I am currently aware) the only way to randomize assignment is by using the subject ID. In other words, I do not know of a way to randomly assign participants to conditions without using a subject ID BUT the subject ID is determined before I would like it to be because some participants are deemed ineligible for the study even though, in the grand scheme of randomness they have technically "balanced" the distribution of the assignments. It is not the ID it self that I am wishing to change per se, rather the assignment function that seems to be inherently tied to the ID.
I am very sorry if this is confusing (because I am pretty sure it is). If anything is unclear I will try to clarify.
