Managing the proliferation of settings instances in Terminal

[Hippo Man]

In Terminal, if I go to Preferences->Settings->Advanced, there's a pane that has literally hundreds of instances of setting configurations, numbered sequentially. Apparently, every time I start up Terminal by selecting a [something].terminal file, another one of these setting instances gets created.

Is there any way to prevent these from being created every time I start another Terminal session in this way?

Thanks in advance.

I just found a way to do this. I don't know if it's the recommended approach, as it's rather heavy-handed, but it works:

/bin/rm -f /Users/hippo/Library/Preferences/com.apple.Terminal.plist

... where /Users/hippo is my HOME directory.

I just set this up to run at boot time and also once a day. Now, my Terminal instances come up in a fraction of a second, instead of taking 15-30 seconds to start like they used to.

I don't use any of the Terminal settings instances, as I use hand-crafted [whatever].terminal files to start my Terminal sessions. Therefore, I don't see any problem with completely deleting that plist file.
