Glue milestone to connection point automatically

[andzus]

I am creating multiple timelines in Visio 2013 by using 'Link Data to Shapes' and importing a list from Excel. Quite a few of the tasks have the same Start Date so to not overlay these I drag them on top of the next milestone and 'Glue to Connection point' (as shown in image attached) and then 'Align right/left' to build a milestone tree.

Problem is that I will have 26 timelines with around 200-300 milestones each, so dragging these one by one will take quite a long time.

Is there a possible way how to automate the dragging/aligning process?

Many thanks!
