Add +DI(14) and -DI(14) to TA Scanner Builder

Please add +DI(14) and -DI(14) as available indicators/conditions in the TA Scanner Builder and Expression Editor.
I would like to use them for Linda Raschke’s Holy Grail setup:
LONG: +DI(14) > -DI(14)
SHORT: -DI(14) > +DI(14)
More generally, +DI/-DI are useful together with ADX because ADX measures trend strength but not trend direction. Adding DI would allow users to filter ADX signals by direction, confirm trend continuation and breakouts, reduce counter-trend signals, and use DI crossovers to identify potential trend changes.
This would be a useful addition for many DMI/ADX strategies, not only the Holy Grail.
