I don't know if this is really bad approach, but I know that we created a separate CA for each form (or each particular operation). The only exception was CASearch where I set SelectCMD on the fly (still same form).

The rest of my CAs always were pre-defined and with fixed commands.
If it's not broken, fix it until it is.
