Calculating video duration in minutes

I would like to include the duration of a video in minutes in its title.
However, I have only found the following option:
<Duration Hour><Duration Min>

Result, for example: 0235

Is it possible to convert this into minutes, which could look something like this:

<Duration Hour>*60+<Duration Min>

Result: 155

Kind regards

The <Duration Min> cannot be used since it only returns the minutes part, not the total number of minutes. I don't think there is a tag to be used as of right now, but you can do it in the script method. Like this:
return Math.round(item.Duration / 60);

If you want to append it to the existing name, you can do it like this:
return item.newBasename + Math.round(item.Duration / 60);
