Using custom variables in "From" of Dataview

Could you please help me how can I use custom variable in Dataview. I have the following variable that contains a path to the folder:


I would like to use it in Dataview in FROM clause something like this but receive an error

	without ID link(, name) as Video,	
FROM this.VideoSeriesPath

one workaround is to use dataviewjs and pass dv.execute() your dataview query as a string, with the variable concatenated into the FROM
