Add A Clickable Email Link with subject and body To A Page

[FlagLamps_com]

When editing a Shopify page, I can add text in the Content section of the page, I can select text in the content and add a link. Does Shopify support adding subject and body arguments with the mailto: feature?

This works fine in the Link to field of text (but as you can see I have not included subject or body arguments, which is my objective):

mailto:ShareMyFlag@flaglamps.com 

This does NOT work in the Link to field of the text (trying to add subject and body arguments):

mailto:ShareMyFlag@flaglamps.com?subject=Share%20my%20flag%20story&body=My%20flag%20helps%20me%20to%... 

This does NOT work either :

<a href="mailto:ShareMyFlag@flaglamps.com?subject=Share%20my%20flag%20story&body=My%20flag%20helps%20me%20to%20celebrate...%0D%0A%0D%0AI%20enjoy%20my%20FlagLamp%20because%20it...%0D%0A%0D%0A%5BAttach%20a%20photo%20of%20your%20flag%20with%20and%20without%20your%20FlagLamp%5D">ShareMyFlag@flaglamps.com</a>

Does anyone in Shopify care to comment on this request? It would be such a better user experience for us paying customers.
