Thanks for all your quick support; unbelievably fast and greatly appreciated!
Although something I've never done with GSAK (only used for challenge cache verificatin prior to this), I made a small GPX file there and was able to successfully import it. Since the individual geocaches have no common denomenator among them, I can't make a PQ to pull them. I'll see if it's possible to make a list on the geocaching site, import that to GSAK, then export to GPX and import into cachly. If the list option doesn't work, then I'll have to import each individual cache to GSAK as I did for the test file. Same result, only slower.
