Promotion choices and multiple items?

I’ve recently started an fe8 hack in febuilder. I thought it would be cool to incorporate different promoted classes through different items. But gilliam has two viable knight crest promotions through general and great knight. I can’t figure out how to allow promotion choices while using multiple items. Can anyone help?

welcome. epicer linked the asm for it, but it isn’t a patch for febuilder already and might require a tad of event assembler knowledge on your part. If you are having trouble installing it, show what you’ve done and we’ll be happy to assist.
