Donations and Multiple Accounts

[Sephiroth781]

Not sure if this is the place or if the subject has been broached before. I've donated and gotten a few perks, but I also have tons of alts and with only 12 characters per account, it would be nice to have mounts on the other characters I have, especially when 2-boxing (not something I do often). Is there any way to "link" a second account to gain the benefits of server donations on them as well?
