Hope you don't mind me posting here. I was using your files (16-04-2018 UK), and decided to switch the main on-top service to Freesat, as less channel changes will occur.
I add the extra FTA channels from Sky (excluding adult and international). Using the LCN file I have grouped channels, but not alphabetically: SD > HD > +1.
Maintaining the LCN is not much extra work, and allows you to organize the channels. It also applies your changes to every new scan.
Any new channels added by Virgin will appear in the last two bouquets after automatic-manual tuning, as a note.

Also, you can connect to your ***receiver*** box via any file explorer. Either type the IP address into for example "Windows explorer" to open the drive, without added software.
You can also connect via the file sharing service, simply open the "***receiver***" from your "Network" list, else you need the IP.
