Hi
There's no dedicated feature that will do this, no.
Snapshots are, among other things, designed for situations like this, though. They allow you apply a base profile, and tweak it from time to time without the need for entering all data each time.
In the coming update I've added a ton of inconspicuous features to the analyzer. Automatic snapshotting and node deletion being two of those. Snapshotting will happen automatically - both in the console and now the analyzer - for any profile curve that is shared when you attempt to edit it. Also, you'll be able to select a node, then long-tap it to delete it. (Another one that may be helpful here is the coming ability to edit all of your curves before starting the roast.)
This works nicely for my Quest, but I'm a minimalist here, and have honed my profiles to be as few nodes as possible, so for me it's only a node or two at most.
How many nodes do you usually delete? If folks would find it helpful, I'm sure there's a way to accommodate with a dedicated feature.
