Welcome to the forum DaniVork.
I doubt if the Layout dimension tool could be made to recognise different dimensioning end points. However, you can set up as many dimension styles as you need within the same Layout file. Use a dummy dimension on the page and sample it with the eye-dropper tool before adding a new dimension. Or, use the eye-dropper to update an existing dimension. Ideally, save your dimension in a Scrapbook to use in future work. The Layout dimension system is very customisable, you could, for example have the astrix you like on just one end of the dimension line.
Good luck!
