Spreadsheet app on iOS: select non adjacent cells

Hello everyone, I have searched online for a solution that indicates this is not possible but I thought I would check with my favorite resource to see if I’m missing something.

I am creating a spreadsheet on iOS for a client that I do social media for. In this spreadsheet I would like to create charts showing increase in followers for each channel. When I try to create a chart there are times when I need to take data from different non adjacent columns in order to make the chart. I have tried Excel, Numbers and Google Sheets, but I can’t seem to find a way to select multiple non adjacent cells at one time. Is this functionality possible on any iOS based spreadsheet application or am I dreaming?

Thank you very much for this community.
