How should you add volume optionality to the eRR Table Trade Entry screen?

The ACER examples (TRUM and TRUM Annex II) give the impression you can enter a range. But unfortunately you can only enter a simple number. 

So if you had a minimum of 0 and a maximum of 50 for January you should enter the data as follows:

(1)   1/1/16-31/1/16   cap = 0               = minimum Jan
(2)   1/1/16-31/1/16   cap = 50             = maximum Jan
(3)   1/2/16-29/2/16   cap = 20             = minimum Feb
(4)   1/2/16-29/2/16   cap = 80             = maximum Feb
