Vote on this idea if you want expand/collapse on column headers in the matrix similar to what was shipped for row headers in November (https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-november-2018-feature-summary/#expandCollapse).

10/20/2022 - Just an update, this is an extremely expensive item, which is why it has not been picked up yet. I promise we will revisit this after we ship visual calculations

RE: Add expand/collapse feature to column headers
Column headers are very useful to expand, I get requests all the time for Fiscal Year or Calendar Year with the option to expand out to the 12 months of a given year, then collapse it and move to the next year over, expand that out, etc...
