I don't think you cover what you want the formatting to look like but if you have the formatt and drop downs in some other cells (maybe hidden somewhere) you could copy and paste them. To take it in steps:
To copy and insert cells:
You would need to create a loop of some kind in order to repeat the code, to do this you will need to set a count variable as the row number to insert and increment this, for example:
Finally, you need to decide on the type of loop - if you know how many times you need to do it, you could use a for loop such as this:
Note - I have assumed that you mean every 44th row as it is before running the macro, so once 2 rows are inserted between 29 and 30, the next two should be between 75 and 76, hence the 46 increment
Alternatively, if you don't know how many times you want to run the loop but there is a condition that will change when you want to stop running the loop (for example, there is no more data) you could use a do...until loop:
