Column "day/week/month" highlight

Hi there,

Is it possible to highlight/shade of a column, whether this is correspondent to a day, week or month?
I can find every option of background colour in “Styles” for lines/tasks, but none for columns in the calendar.
We would like to reinforce some of the critical deadlines/days within a project.
Thank you!

@Diana This is not currently possible to do in OmniPlan, sorry! We do have an open feature request for this functionality - I’ll add your note so that the rest of the team is aware that this would be useful in your workflow.
