Vertical Hist. Delta - Change TF Volfix Anywhere

Hi,

is it possible to make a setting that you can Sum the Delta in Vertical Hist for a specific TF (at the moment its calculated by the TF that im using in Boxchart - 1M , minute per minute) 
it would be cool if you could make a setting to calculate the TF for BOX1/BOX2 TF so you can see the delta in for example 5 Minutes. 

i made a screenshot for better understanding

Thank you
