Yes, though I noticed an interesting and useful thing when refuelling some of my Proportions fleets using tankers.

I made a "refuelling fleet" consisting of several ships which could use some supplies, and a couple of nearly-full tankers with heaps of supplies each. All of the regular ships were topped off, as expected, but the supplies came from only one of the two tankers. The other tanker didn't give any supplies to anyone. This is quite useful, because then one tanker can remain in the forward position, while only the one that gave supplies can go back for more.

Of course, I could have done the same sort of thing manually by only putting one tanker in the resupply fleet.
