Can I use the same field in 2 different tabs ? on the same Module?

Hi Team,

I have a field called 'Platform' that I would like to show in 2 different tabs under my Accounts module. Is this possible?

If not, does anyone know how to create a field that would copy the selection of another field? I.e if 'Platform' selection was "Cloud" the new field would automatically populate to "Cloud" also?

Thank you
