Best Custom Calling for TabCaTS Service Missionaries?

[RBeatse]

We have a couple where the brother is in the the Orchestra at Temple Square and the sister works with the Tabernacle Choir at Temple Square managing the sheet music. They have callings as Musical Service Missionaries but in LCR they show as having no calling.
Would you put their callings under Other Callings | Music | Custom Calling or Additional Callings | Custom Calling or any other ideas on what someone has done in their circumstance?
I know it doesn’t really matter but wanted to see if there was a concensus on where it should go.
