I had previously failed to note the "Eliminate candidates..." option to STV. But having noticing it, I am able to follow Ciaran's suggestion and run repeated Condorcet cycles over last year's ballot until 7 members are selected. Running STV in this manner selects the same council as we did elect. Total effort --- perhaps 15 minutes work for a new election (I have scripts which will build a master ballot from a collection of individual ballots, and from that the effort is minimal --- say, 60 seconds total if you are slow.) So, my "tedious" comment is someplace between misleading and wrong. I note in passing that NO voting method designed to select a set of several winners at once for this sort of election chooses quite the same winners as repeated application of Condorcet does. The deterministic one do agree with each other, however, on a slightly different set of winners. At some point after this year's election we should follow up on this.
