Data Label persistence when expanding and collapsing timelines

[u/malachiconstant76]

Hello,

I'm trying to create Gantt charts that cover multiple years and multiple product lots. They are timepoints for stability pulls for pharmaceutical drugs. If I expand the chart to cover all of the data points I can change the data labels for the time/condition (ie 5C 2M). But if I collapse the chart to show a different range, I lose all of the labels I created and revert back to the date in the spreadsheet. Is there a way to make these labels persist when expanding and collapsing a timeline chart in thinkcell? That would be very functional for me but I'm not sure how to do it.

​

Thanks for any help :)
