API POST calls timing out

When I make calls to an external API via the API block (POST), if the call runs for more than 60 seconds, an error is generated which says, "Unable to fetch response".

I need the API block (POST) to wait longer, since the responses sometimes take more than 60 seconds.

Is there someplace that this timeout value can be set? I have no way to shorten the time the calls take as calculations are being performed that are out of my control. I know the server is working at the other end because I can see the response being sent by the server after the timeout occurs.

I have searched the documentation, this server, and Google and I cannot find this answer - but maybe I'm just not looking in the right place...
