Remove/add the extra rows between two blocks in webi

I have 2 blocks in webi side by side, based on the selection of Account id block shows selected Amount/Data in each block.

output of the report: Block 1(1 row) for 1st Acount ID | Block 2(2 rows) 1st Acount ID

and  Block 1(1 row) for 2nd Acount ID | Block 2(1 row) 2nd Acount ID

I need to keep the data in Block1 same number of rows as Block2

I need to add the extra space after 1st acount data of block 1 .

It is not a cross tab report. My intension is to keep the data in both blocks should match with the Acount ID

Did anyone come across this type os issue. Let me know your thoughts.

Attached the sample one.

Thanks in advance
