In the assembly module you can use the merge parts (Boolean) feature. Note there is a checkbox whereby you can keep the internal faces.
Otherwise, if you just have one volume (cell) you can use the many partitioning tools to subdivide the cell into multiple structured/sweep meshable cells. (There have been many improvements made in V6.6 to sweep meshing that make it much more forgiving to your topology)

Extra bonus tip:
For those of you who think you've exhausted the partitioning options (even though there are quite a few), there is a nice trick you can play:
To partition a cell, you can actually create a shell feature (extruded, revolved, lofted, etc) and look at the dialog box before you finally create it. There is a check box to say "keep internal faces". This will have the effect of "partitioning the cell. I find this particularly useful with the shell loft when the shape of the partition you want to make is quite difficult...
Finally, as one more bonus:
You can actually make multiple partitions at the same time. Just try it with extruded shells (sketch a whole bunch of circles to create extruded "tubes". Use the "keep internal boundaries" checkbox, and watch what happens!

Thank you brep for your fast and very helpful advice. I managed to merge parts and keep partitions.
I need one more advice. How to solve incompatibility between regions? When meshing some partitions I get warning message that incompatible mesh (incopatible element shapes) will be created. It is transition from structured to free meshed region.

You can try to make both regions hex meshable (structured and/or sweep), or you can accept the incompatible mesh info message, which is actually fine if you don't mind having a tie constraint in there. (Tie constraints used to be a dirty word in FEM, but ABAQUS has some specific technology to make such constraints much more acceptable these days)
