Daily Reward Crates, Mk3 Ability

I really appreciate the opportunity to get daily rewards from the SWGOH webstore and now the PC client as well, but I'm finding that the Mk3 ability material as the only ability material is really not as useful as it was initially.  I'm currently sitting at 3106 Mk3 ability material, but have virtually no Mk1 and over 800 of the Mk2 materials.  

Is there any way that the daily crates from those locations could have randomized rewards? Sometimes Mk1, Mk2, Mk3, or even in a VERY rare instance, Omegas or Omicrons?  It seems like the fact it's 20 every day of Mk3 rewards becomes too much based on how I have more than I think could be conceivably spent on the entire character base.

Thank you!
