Absolutely. You have two options:
Reclaim Hosting support can set up an invoice for you for a certain amount of money that would be added to your account as a credit. Future invoices would first draw from that credit. This is good if you don't necessarily care what's getting renewed and for how long and just want to add $X dollars to your account.
Alternatively, Reclaim Hosting support can setup invoices well into the future for any accounts/domains you'd like. We'd just have to change billing periods and generate them on our end.
Let us know what you'd like to do by sending a support request to firstname.lastname@example.org.
