Need Short Thin Tubes--ReSound

I just had thin tubes installed on my 2019 of BTE ReSound HAs. These are now my backup HAs (as I also have new Jabra Enhance Pros).
BUT, the new thin tubes are too long! My audi says he’s unable to get a shorter size, but he’s “asking around”. Mine are marked “2B”. Does anyone have access to shorter thin tubes for ReSound that we could obtain?
