Firewall Alias - URL Table (IP) : deduplication?

[litebit]

Hi,

I've a question regarding Firewall Aliases (the URL Table type)
When I add more than one URL, each pointing to a different list of IP networks, if between those different lists, some networks are the same, or listed multiple times, does Opnsense automatically do depluplication (I mean, when building the internal table for this alias, list those duplciate networks only once)?

Thanks
