Linking Child Timelines to Multiple Parents

[Campbelldw]

I have a Visio 365 Pro timeline drawing which I am importing data to from excel. I have got a primary timeline and 2 levels of children. The first level of child is a breakout of one section of the parent, for example 1 child goes from 11/1 to 11/16 and the other goes from 11/17 to 11/30 as these are the 2 different activities to take place during this month. Now there are some child activities I am trying to break out on a second child level that start in one and run into the other, for example the 2nd child would start on 11/10 and run until 11/20. But due to the fact that this crosses multiple timelines I cannot seem to get it to to it properly. Does anyone know if this is even possible within the application? If it is could someone please let me know how to do it?

Parent Timeline 11/1/2018 - 2/1/2019 (Broken into 4 segments)
Segment 1 (Parent Timeline) 11/1 - 11/30
Child Timeline 1 Task 1 11/1 - 11/16
Child Timeline Level 2 Primary Parent (3 Tasks) Task 1 11/1 - 11/10
Task 2 11/10 - 11/20
Task 3 11/1 - 11/16
Child Timeline 2 Task 1 11/17 - 11/30
Child Timeline Level 2 Primary Parent (3 Tasks) Task 1 11/17 - 11/20
Task 2 11/06 - 11/25
Task 3 11/10 - 11/20
Task 3 11/20 - 11/30
Task 3 11/17 - 11/30
thanks
