Memories do not store screen Span persistence between cw and phone

I operate CW and SSB. I have memories for each band for SSB and memories for CW. The memory stores filters, step size, VFO frequency fine.

But, on CW I like to set the spectrum display span to cover the bottom 60 khz of each band. Example 3.500 to 3.560 and on phone 3.600 to 4.000 

When I change from one memory to another the spectrum display changes to the target frequency in memory but the span or range of spectrum display stays where it was before.

Example: I am on CW with a span of 60 khz. I select a phone memory and the Display jumps to the frequency in the phone band stored in the memory BUT the span is still 60khz on the phone band not a span of 400 khz like the last time I stored the phone memory. 

Am I missing anything? Every time I switch from phone to CW or CW to phone it takes me time re-adjusting the spectrum span to cover the band.

Rig is the Flex 6500 running the newest software. I think it has always operated this way with the older versions of Software. 

Not the end of the world the Flex is a great rig but this would be a nice feature for us CW and SSB operators. 

If I use 2 Flex 6500's one 6500 set for all the phone spans and one 6500 for all the CW spans and just use the Band selection menu it works fine. 

Any thoughts?
