Macro help: /additionalaction and error messages

I'm trying to set up a couple of macros that toggle between a couple of sets of additional actions for different purposes (specifically, one set for a very specific rotation for 2* crafting and a different set for lower level recipes with abilities I'm accustomed to having.) Since the set of skills that are actually cross-class actions varies by class and I can fit more or fewer of the skills in on some of them, I am attempting to set up a pair of macros that do the following:

- Remove abilities from set 1 (e.g. /aaction "Rapid Synthesis" off)
- Add abilities from set 2 (e.g. /aaction "Piece By Piece" on) - some of these may fail because they are native skills to the job I'm on.
- Add abilities from set 1 back in, knowing that some of these will fail due to not enough cross class slots left.

That last part throws a bunch of error messages into my chat log, and I'm trying to find a way to suppress them while running the macro. I've tried the commands /macroerror off and /actionerror off and neither one does anything, and I can't find any other similar commands to try.

Does anyone have any ideas for how to do this? Or am I going to just need to suck it up and accept that error messages will happen or make separate macros for each job?
