Custom line annotations in SDR?

Roger_W6VZV

Having more fun with my Flex 6400M than a human being should be allowed to have.  One thought that I had.  Could Flex consider a feature in SDR that allowed a custom line annotation on the frequency part of the spectrum.  To clarify, what I mean is, for example, a feature that would enable an annotation say, at 14150 that would show a vertical line with the legend "Phone band edge" or something like that.  Or at some other freq with "XYZ Net Freq." or somesuch.  Just a thought.  Make it custom so that those who don't want such annotations don't have to look at them.

Could also show if a memory has been established for a displayed frequency.

Not that it has been designed for it but you could put a narrow TNF filter on those points and lock them in place. 
If you put them right on the Zero Beat line it at least won't hurt on SSB because the Passbands are 150 Hz above or below zerobeat. 
Maybe this will temporarily work for what your wanting to do.
