Organising EPG

First of all thanks to this group. My current annual sub just ended and a thread at teachings pointed me here.

Anyway, I've just signed up for 3 months of STRONG 8K. I use this on 3 devices - 2 x Tivimate and 1 x smartersTV.

The EPG and channel list is huge and id likely spend hours sorting and arranging using a tv remote, and then have to do that on multiple devices. Is there a way I can do this on a laptop / PC and then send the amended channel list to my devices?
