Adding the 'Edit' option for Triage that is normally accessible when viewing questions and answers, including from review 'First Posts' and 'Late Answers,' I think could help alleviate the problem.
As 'Requires Editing' should be clicked when the reviewer thinks that the post can be appropriate with editting, the reviewer may be able to make the edits himself. However, there is no option for him to edit the post itself unless he wishes to search for the post manually before or after he triages. Having to manually find the post in triage, which isn't as easy as with the other reviews, is offputting. It can also safe effort from the moderators if reviewers can make or suggest the edit themselves.
It can also help reviewers decide if the post should be selected as 'Required Editing' or 'Unsalvageable' if they can actually attempt to edit the post into something that would warrant 'Ok.' This could be seen as testing the 'Required for Editing' requirement with a hands-on method instead of simply reading. For example, this recent post which I had previously (and genuinely) thought could be fixed with editing from someone other than the person asking it (I thought the information in the question and the code could have been used to clarify the text that should have more clearly explained the question). However, when going back to it afterwards the next day following a review ban, and attempting to edit it manually, I realised I couldn't adequately edit it, and a 'Unsalvageable' or 'Skip' was more appropriate.
