Have had a read through the manual below and have not seen it mentioned so guess it can't be done.........yet.

For areas where CM93 is lacking, sometimes SASplanets CMap overlay provides more information and I save it as an MBTile and put it in a separate folder called MBCharts so as to keep it separate from the
satellite MBtiles.
I then run my
screen in dual mode, only cm93 selected in chart groups on one side and all selected on the other but there is no way to know which tab is MBCharts without clicking, clicking and more clicking closing off tabs.
Is there a way of selecting cm93 and the mbChart folder only on one side so when I come into an area that is lacking there will only be the MBCharts tabs to toggle, not all the
satellite imagery as well?
I did think that putting the mbchart file in with cm93 may have worked but it did not.
Thanks.
