Default Manual ECM request missing cofactors

When requesting work type "ECM on Mersenne cofactors", either manually or via Primenet, the entry in worktodo.txt includes the existing cofactor(s) [0], e.g.



ECM2=____,1,2,274199,-1,250000,25000000,150,"548399,3269797932048497"


The Primenet assignment details page does not include the cofactors, e.g.



ECM2=____,1,2,274199,-1,250000,25000000,150



The issue is that, as documented in undoc.txt, by default ECM will stop when a new factor is found. The known cofactor is then reported as a new factor. Is there a reason not to provide cofactors on the assignment details page?

Just want to bring this issue to attention since it hasn't gone yet. The entries produced on https://www.mersenne.org/manual_assignment/ are fine but those on https://www.mersenne.org/workload/ are missing the known factors.
