Trying to move documents around within "OmniSweet"?

Greetings,

I am testing outliner, focus, graffle and omniplan to buy and use, but am unable to move files between them.

Two days have been spent reading manuals and forums and no relevant information has been found…still don’t understand if this is feasible.

May I ask to be pointed in the right direction, please?

My intention is as follows:

  1. brainstorm for ideas and objectives using outline to make notes
  2. import to omnigraffle and create hierarchies
  3. importing to omniplan with hierarchies to set timelines
  4. follow up and keeping track of time with omnifocus

NOTE: have also tried many different export/import/open formats to no avail

Thank you!
