Is it possible to remove IP that belongs to blocked list in CIDR range?

[MaXi32]

To demonstrate this question,

Let's say I have this 3 IPs:

1.1.1.1, 1.1.1.2 and 1.1.1.3

Now I want to block each of this IP individually using csf. So,

csf -d 1.1.1.1
csf -d 1.1.1.2
csf -d 1.1.1.3

Success, now all of them are blocked in /etc/csf/csf.deny

But then if I want to block 3 of them using CIDR /24 notation. So I did this:

csf -d 1.1.1.0/24

Success, but CSF did not remove the previous 3 IPs and this looks redundant to me. Also when removing csf -dr 1.1.1.0/24, it did not remove all IPs belong to the network 1.1.1.0

Is there a hidden function that CSF can handle this or do I need to manually delete the entries after using CIDR block?

Anyone willing to answer this? Do I have to create my own script to remove this duplicated entries ?

It's sad to see that all of my posts that I asked (if u look at the history, nobody is answering) except me giving my own answer. Shed some light on this please.

Answering my own question again after searched about this on the internet csf not able to do this on its own and I have to manually wrote script about this. Successfully wrote this script.
