Create new scenarios within load editor of qlik sense

[Anonymous]

Looking for help from this genius body.  I'm trying to create a dimension using a variable that will reference a dimension & month combination but getting nowhere!  The table below is an example.  My model is quite larger than this, but this simple example is the problem.  I want to create a full year scenario called "Cur Fcst" that will pull Actual Jan, Actual Feb, 2+10 Forecast Mar-Dec.  How do I do that???

Scenario	Month	Revenue
Plan	Jan	100
Plan	Feb	200
Plan	Mar	300
Plan	Apr	400
Plan	May	500
Plan	Jun	600
Plan	Jul	700
Plan	Aug	800
Plan	Sep	900
Plan	Oct	1000
Plan	Nov	1100
Plan	Dec	1200
Actual	Jan	150
Actual	Feb	190
2+10 Fcst	Mar	250
2+10 Fcst	Apr	275
2+10 Fcst	May	345
2+10 Fcst	Jun	415
2+10 Fcst	Jul	485
2+10 Fcst	Aug	555
2+10 Fcst	Sep	625
2+10 Fcst	Oct	695
2+10 Fcst	Nov	765
2+10 Fcst	Dec	835
