double click select variable with a dash

with web components up and coming it would be nice to be able to double click and select an entire variable even if it is not a single word but seperated by a dash
Example
<my-webcomponent></my-webcomponent>  
So in the above case if I double click on my it would highlight the whole word my-webcomponent.

Is there a setting where you can specify the doubclick highlighting criteria?

Thanks,
Dan
