Yes you can do this easily. You can use this block
b768bfd2b86c233174149b67b68816ff9c60d9b3
And set your number from (1) to (29),after that if you want to create list for/of 78 then, set from(30) to (78).

Thanks

you can try this

no , i have to do this in dynamic component , automatic select the number , like if lenth of list is 3 so , like eisode 1 , episode 2 , episode 3 like this

I think you want to say if episode one is completed then call episode in a list.

no , i have to say that if i calling data in csv format then according to data length , the text created in counting like episode 1 , episode 2 , episode 3,

Can you tell me with a example, bcz I am confusing actually what you want to say, tell me via personal message.
