Change e-mail share subject

Currently, the email share button shows the following:
mailto:?subject=Check%20this%20https://ourwebsite.com/offertelijst/?wishsuitepids=293,305

Is it possible to change it to (for example) the following:
mailto:test@example.com?subject=Whislist&body=My whislist: https://ourwebsite.com/offertelijst/?wishsuitepids=293,305
