How to Load Multiple Stamps, and Reorder Stamps in Adobe Acrobat?

I make a lot of similar comments/mark sections with stamps in Acrobat. I have my own color-coding/marking system I use. I found I can't select multiple stamps to upload at one time.  I created several sets of stamps, each set with 11 color/transparency variations. I wanted to upload each set at once, but had to upload them into the stamps feature very tediously, one at a time.

I also cannot reorder stamps once I upload them. To reorder, it looks like I have to delete and reupload ALL the stamps from that category all over again. It is excrutiating. 

Am I missing something? I go to stamps and click the "manage" option, but it's just as painful to use as the "create" option. I should be able to add multiple stamps at a time. I should be able to reorder them. I don't understand! Please help!
