There might be something in this thread that helps:

ok I place note using the standard tool place my leader arrow head where I want  and the tail where I want  then place a space in the text editor data point and close the text editor one leader done now if I need more  I just copy paste and  use the handles to modify it..

You could do the same in a cell then just attach it as a cell drop it and use the modify  handles etc to make it look the way you want.. if you do it alot you can use a function key to call up and  place the cell...

ac=<path to cell> .. personally I just use the macro recorder do the steps to attach my cell  and  then edit to suit my needs for placement ie wait for my data point.. then use the macro to bring it up each time ie  key in macro arrow or copy  the active part of the macro as a script in the function key usually it will be just a single line of text that is the command to go get the cell and wait for data point placement...

have a go at  it what ever suits you  the cell thing works well because you can choose the scale to use..

For my own needs I just use the standard place note  and  put a space in the word processor.. but there are 100 plus ways to skin a cat .. and  something I mentioned may  prompt you or others to use the work flow for something else.. well that'is how I learned how to do most things in microstation by coming up with work arounds or different work flows...
