Vocal Score missing some clefs

I see that Notion for P iPad now has vocal score capability which is fabulous.. But some obvious clefs are missing.
For example when doing a capella vocal music it is very common to use a Treble clef with a 8 under (indicating sung octave lower than written) for Tenor and "Melody" parts.
For example You might have a
- Tenor Parts with Treble Clef and 8 Under indicating sung an octave lower than written
- Melody or Lead voice - Ditto
- Baritone would be say Bass Clef
- Bass would be Bass Clef.
This is very common is Male only a cappella (Such as barbershop or some do-whop styles) actually similar applies to female only a capella too.
There are probably 20+ clefs available to musicians to use .. It would be nice it they were "all" available within Notion?
Please update the clefs in Notion to allow these variations - or tell me how I can do it if it is available as I cant see the option in the Vocal staves I have just tried to set up.
