Use of access path to decide whether to use NATIVE / SQL mode

We have several unloads that use HPUs with SUPPORTED select that download UTS PBG.
Queries are unfortunately written by programmers who can change them independently and often don't know how many rows they will have to download and therefore they don't know if it is more convenient to use SQL MODE or NATIVE MODE. Often we have queries that with SQL MODE would be optimized with the use of indexes but using as default DB2 YES HPU decides to use NATIVE MODE and scans all the vsam consuming a lot of cpu and very high elapsed  times to download a few lines.

Now when we intercept these cases we ask the programmers to use DB2 FORCE

We opend pmr 15863,830,758 but we were told that hpu works as it was designed
