Thanks for your suggestions. I will try out the action group recommended by @FlohGro .
One thing I notice is that my drafts tends to be around notes taken for the same customers, just that they come in on different days. This is where the Merge was really useful and I just decided recently that once I have merged them, I will trash the individual drafts, so that IF I end up using Drafts as a filing system, I don’t get duplicates when searching.
Edit: I just learned that I can append into an existing drafts from quick capture!
The one thing I need to figure out is how I can have a timestamp printed at the top of the drafts when I create them using the quick capture shortcut (CTRL-SPACE, in my case, in a Mac) so that when I merge them, these drafts are separated by timestamp. I think there is an action on merging that does this. I have to search for it this weekend.
