testing if a named set exists?

[Matt Zagrabelny <mzagrabe@xxxxxxxxx>]

Hello,

I'd like to do something like the following:

if exists $named_set
    nft add rule ip filter output ip daddr $named_set accept
else
    nft add rule ip filter output ip daddr $default_set accept

Does anyone know if I can accomplish this with nftables?

Thanks,
