I wish there were an option for "recurring slips" as well as recurring invoices. For example: I have a recurring invoice for a client (quarterly) for web hosting. I have another recurring invoice (same client) for domain registration (annually). When the domain deadline arrives, I see two invoices for the same client, which I have to clumsily combine along with whatever other items might be on that invoice.

What I'd like to see show up in the slips pane are any recurring slips, which I can attach to the current invoice. This would significantly reduce the time I spend in Billings shuffling items around.

Basically, the slips should be recurring, not the entire invoice.

I hope I'm making this clear. Let me know if it doesn't make sense.

Thoughts?
