Anything is possible.
It's not clear what you'd like, though. Do you want to be able to select a channel by asking for:
a. *either* the channel number *or* the channel name?
OR
b. the channel number *plus* the channel name?
OR
??
Basically, you need to edit your payload XML file to use the phrasing that you want. The value needs to remain the channel number, but you can edit the phrases column.
You could either customize the SQL query that is used in the xSql plugin to generate the payload XML files (unless you're using mySQL with Kodi, in which case edit the xMySql plugin query) , or manually open and edit the payload phrases in the payload XML file, within VoxCommando's command tree editor.
Personally, I'd do the former.
