Expanding dynamic item list

Hi there,

according to the template an item list may have 100 entries. My question is how to best increase the number:
a) is it a dynamic array so adding more entries to the template works?
b) can I add more item lists for the same level in level tables? e.g.
levels,1;15;15;42;42;60;60, records,records/items/loottables/misc/tdyn_potions_a01.dbr;records/items/..
c) or add another entry in the master table?

thanks in advance

Another entry in the master table
