So I have a couple of themes available on my sites for users to choose from. The regions don't match exactly, but I do want the blocks to appear in both templates. How do I set the default location for a given block when a theme is set as default? I want something like hook_template_default, but that of course does not exist.
EG, say I have a contact Information block. In theme1, I want it to appear in the "sidebar" region. In theme2 I want it to appear in the footer region. I don't want to have to go to blocks and manually reset this every time I switch themes. Is there a hook or other way I can accomplish this?
