For some reason I am not able to input a Portamento marking for my cellos section, but I was able with my violins.
I have attached a screen shot. I have gone into the engraving mode and was not able to manipulate this marking even there also.
Any advise would be so helpful.
Screen shot is provided - I wish it to happen from bar 10-11 as the Violins as you can see.
Thank you in advance if any help is out there!
