Can you use campaign tokens in email flows?

Hi -

My sales team is looking for us to create custom landing pages and email streams based off of campaigns they set up. One of the fields in the campaign set up requires them to set an account name. We can't use the account tied to the lead for a few reasons so we can't use that field.

Can you set up custom campaign fields and have them work as tokens? I tried it but can't seem to find it in Marketo.

Thank you
