Define a transaction and call the same transaction multiple times.

I have a set of steps declared as a transaction in neoload and I want to use that transaction multiple times. for better understanding of the scenario I will use below example.
transaction_1{
Step 1
Step 2
Step 3
Step 4
}
transaction_2{
Step 1
Step 2
Step 3
Step 4
}
Switch(a){
case 1:
do something
transaction_1
transaction_2
do something
case 2:
do something
transaction_2
do something
case 2:
do something
transaction_1
do something
}
can we call already declared transaction at later point so that it would look little less messy ?
