LR mobile with Apple Premium Subscription and trialing LR desktop and then possibly cancelling

Hey folks.

I use LR mobile on an ipad and live it.

I use an Apple LR stan alone subscription which gives me Premium.

I want to trial LR desktop on top of that so I can import some presets that havnt been adapted to LR mobile.

I know there is a way to do it but it's drawn out and you have to do it one by one.

If I trial desktop and import the presets into desktop and them transfer to mobile LR , can I then cancel the 7 day trial and keep all the transferred presets and my Apple subscription for mobile?

I don't need and wouldn't use Desktop normally.

An ipad Pro does a good enough job for my needs at present.

Thank in advance for advice.
