[GSAS-II] Unable to index magnetic reflections

[אלעד כספי]

Thank you for your answer.
However, I believe the answer was targetted at issue #1 in my mail. Issue
#2 deals with manually (without Bilbao) adding a magnetic phase. In
this case, I am unable to see the (new) indices related with the magnetic
phase when I try to see what magnetic symmetry fits the reflection. Is this
being handled as well?
