No, there's no easy way. I've asked for it before, in a different thread (too lazy to look up the link right now). I'm in the same boat as you are: I often send multiple invoices to a single client.
There is a workaround besides creating the email; it's not the most straightforward, but it works. Here's how:
1) In Billable, click "Preview" for each and every invoice you want to mail. Don't close the Preview windows.
2) In Preview, pick one file (it doesn't matter which one); command-click on the file name in the title bar - this will show you the folder hierarchy. Click on the parent folder (Tmp-something). This will open it in the Finder.
3) In this folder, you should see copies of every invoice currently being shown by Preview (the filenames are the invoice numbers). Now, you can drag these to your email program to attach them to a single email. You can also drag them to another folder to "save them to disk."
I really hope this functionality gets built into the next version, but in the meantime, the above is how I handle things... hope this helps.
