In my case I store items that belong to the FC on one of my alts' retainers because there's not enough room in the FC chest. I'd be upset if my personal items ended up combined with FC items so I didn't know how much belongs to the FC and how much to me.

If you have a system to organize how you will store items before you give them to a retainer, your idea wouldn't be necessary. As an example, put items gathered through mining and botany on one retainer, everything else on the second retainer.
You should have the option to choose where you put your items which is the case right now, the point of this is so you can consolidate the items if YOU CHOOSE SO.
