If I understand what you're doing correctly, you would set up separate auxes for each delay and have sends from your tracks going to those. Then it would simply be a matter of routing the outputs of the delay auxes to another aux with a verb on it, no?

Or if you really wanted to get complex you could mute the outputs of the delays and use prefader sends to send a different volume from each delay to a couple or more different reverbs I suppose.

You could do that easily in Pro Tools or Harrison Mixbus/Ardour (which has the most flexible routing I know of).

I imagine this wouldn't be hard to do on most other DAWs either, I'm just not familiar enough with all of them to say.
