Ability to disable individual ticket prices on per show/event basis or create copy of existing list

Currently setting up a series of practical dance workshops that are priced the same as other events we've had previously. Gone to re-use a price list only to realise it has "Wheelchair User" as a price type.

I'm sure wheelchair users would of course be welcome to participate in their own way or watch others if they really wanted, but we don't need it as a separate ticket type on this occasion & think there'd be a few raised eyebrows if it was included.

I'll need to make a separate price list for now, but thought it would be a useful feature in future if we could "uncheck" ticket types that don't make much sense on a particular show/event where everything else ticket type/price wise would be the same. 
Had similar instances in the past where prices are otherwise identical but a particular show is for ages 16+ & therefore doesn't need a Child ticket type.

Would save a lot of time making additional price lists on top of what is already a very long list for us.

Failing the above, the ability to create a copy of an existing price list complete with price types/descriptions/tags would be good alternative or addition. 
Deleting 1 ticket type from a copied version would be faster than recreating 6 ticket types from scratch.

Setting ticket type priority & tags is often forgotten about when creating new lists I've noticed so we try to reuse existing lists as much as possible.
