Feature summary (what you would like to be able to do and where):

There exist allready the filters (EdittimeFilterPageGenerator, UserEditFilterGenerator) however they cannot be accesed by the standard scripts. I think there are real scenarios when this feature could be useful.
Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
Let's assume that on a number of pages (the list preloaded by an existing generator e.g. -cat or -prefixindex) following changes should be made: {{A}} → {{B}}, {{B}} → {{C}}.
If for some reason the whole process stops (blackout?), we have an inconsistent state that requires either a roll back of allready made changes or some handwork.

Benefits (why should this be implemented?):
Even if this feature would not be often used I think it is convenient to have it as a kind of bailout in such cases. The bot could simply skip the edits made so far.

There has been allready a similar request T57042
