Removing prefixs

I am looking to use a token in one of our email..... {{lead.User Domain Name}}

however....when this populates it also contains the prefix http://www. or www. (obvioulsy this should happen)

but in our case were looking to just website name without a prefix because we are placing it after.......
mail.{{lead.User Domain Name}}

Is it possible to remove prefixs? I was thinking of in the flow maybe there is a way to populate a new field without the prefix and from there using that new field token.

Riddle me that people!

Thanks,
Barry
