Bulk add VG mgcp lines/endpoints question

[Bekzod Fakhriddinov]

Hi, I have to add 48 endpoints on Vg320 with extensions on them. This https://www.cisco.com/c/en/us/support/docs/unified-communications/bulk-administration-tool/118882-config-vg-00.html   guide didn't mention if its possible to add/edit only 1 VG and without messing with current working Vgs . Is it possible, or import will update all VGs? 

Also If the VG created, slot and subunit selected BUT port type was not chosen for all 48 ports, can i update that port type (as pots) together with DN information during  that import/export process in csv file? 

Thank you

Update will not change current devices if they are not modified. Also you can leave only Entity where you doing change and delete other entities, so they will not be affected, http://webmaxtor.blogspot.com/2019/03/cisco-vg350-bat-to-add-or-update-lines.html.

This import/export doesn't change anything for mgcp VG ports and lines (DNs). I have to modify each port one by one manually adding new extensions.
