How to put multiple subreports in a row based on a parameter

Hello All,

I am working on a report that has tablix. My report is like this

I am stuck near the Code definitions (last section). It is a tablix. 1st row has just Code definitions as text and the second row has the table names (LinePipeBendType, LinePipeManufacturer, LinePipeType, LinePipeSeamWeldType). I have 4 subreports for LinePipeBendType, LinePipeManufacturer, LinePipeType, LinePipeSeamWeldType. In the Code definitions section when I expand LinePipeBendType I want to display LinePipeBednType Subreport and when I expand LinePipeType I want to display LinePipeType Subreport and so on. Is it Possible?. Please help with any kind of suggestions.

Thanks
