Convert Queries to Custom Queries & Left Side formatter

It would be fabulous if regular queries could be converted to custom queries with a simple button click. I often get quite far into creating a query to realize I’m going to have to do custom and then end up having to recreate the whole thing. I usually go into the code and grab the sql, paste that into the custom query and fix up the formatting which works ok, but just a straight transfer over would save loads of time, especially if it converted all the parameters and conditions properly.
