Text Cursor position variable for "Insert Custom Text" action?

In the "Insert / Type / Paste Custom Text" action, could there be a variable to position the Text Cursor in a specific spot instead of relying on "Move Text Cursor Left after pasting"?

Use case: I have an action that takes the selected text and wraps an HTML link tag around it. Super useful! It would be great if I could position the text cursor to always land in the spot where I need to add the URL. Imagine a variable named (BTT)@textcursor(BTT):

<a href="(BTT)@textcursor(BTT)">(BTT)@selection(BTT)</a>

In the code example above, I can't use the "Move Text Cursor Left after Pasting" because the length of @selection is unknown.

Thanks! Happy to answer any questions!
