I tried ChartPro in V6 and notice that the V6 Select Channels filtering is filter Object only. When I open the Object I see all channels were listed down, like below:
The old approach was inefficient because the app had to load a view to know what channels are included.
Probably we should improve the Select Channels form to provide additional channel filters which use the configuration database structure to select channels without loading views.
Currently, may be creating several objects and binding channels to them can help to find channels.
