email “other text” from Dropdown menu

Is there a way to get the “first” item listed in a DropDown menu be the part of the text that gets emailed out? Specifically, here is what I have in the form tab:

<label> Membership Type (required)
[select* MembershipType include_blank "Renewal - $25|25" "New (current year only) - $25|25" "New (1/2 year + next year) - $37.50|37.50"] </label>

And here is what I have in the email tab:

[your-name] has filled out the online membership application.  Here are the fields you need for the membership:

Membership Type: [MembershipType]

Here is what shows up in the email that is sent out:

Chris Barnes has filled out the online membership application.  Here are the fields you need for the membership:

Membership Type: 25

What I would PREFER that last line to say is “Membership Type: Renewal – $25”

Is this possible?
