how to hide multiple accounts

[Steve Nospam]

I am a new user who just converted from Quicken.  I am really liking GnuCash but I have lots of accounts that have historical data but are not currently used.  I would like to find an easy way to hide them.  I'm willing to do an export/hack/import if that is what is required or other hack.  The only method I've found so far is to edit each account individually and check the hide box. That's way too tedious.  Any ideas?
