Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
I've tested in locally, it seems like that is no easier way to customize this if you would like to make those icon clickable as well.
In order to make that link clickable, it required some of the data attribute so the Javascript part can able to do something on the page.
For example this repost data attribute.
https://www.screencast.com/t/pcMWX3oOx , and you can't hardcode those data attribute value into that code file, because each of the stream item also have their own different value, so it involved a few files to customize this.
If you urgently need this, I would suggest you that request for a quote from us at
https://crm.stackideas.com and select "Customizations" . Our sales person would gladly send you a quote for the customization that you have requested.
