how to set a firewall address list group

/ip f add add list=mylist1 address=172.16.3.5
/ip f add add list=mylist1 address=172.16.3.65
/ip f add add list=mylist1 address=172.16.3.22
/ip f add add list=mylist2 address=172.17.2.225
/ip f add add list=mylist2 address=172.17.2.21
/ip f add add list=mylist3 address=172.20.0.56
/ip f add add list=mylist4 address=172.31.100.8

for exp ,i want set mylist1-4 forward deny , i need set 4 ruls to drop (src-address-list=mylist1 …)

if have a fuction to set like mylist-group1=mylist1,mylist2,mylist3,mylist4

and i can just set 1 rule to deny the group, (src-address-list=mylist-group1)

There are no lists of lists.

And it’s a pity, because ipset (which is probably used internally) does support lists of lists, together with other useful lists types (I would very much like to have its hash:ip,port list).

In other brands of products, routers or firewalls, many have the function of list group, which is very convenient to use

It’s really a pity that there is a list group function in other brands of products. It’s very convenient to use. I’m looking forward to introducing this function

Seems so logical… a no-brainer?
