On the miracles on Independence Day and Jerusalem Day

Hello Rabbi Michi,
What is the Rabbi’s opinion on the possibility of adding “about the miracles” in an appropriate wording on Independence Day and Jerusalem Day?
My basic assumption (which can of course be disputed) is that there was indeed a miracle here, so the question revolves around the issue of the prayer orders: Is it permissible to add additions for public needs in the last three blessings? There is a discussion about this in the column on the subject of additions in the Shulchan, and as is known today, they are added following the ruling of the Shulchan. Ostensibly, in the Nadad it is even simpler, since an addition on miracles already exists in this place, so there is no fear of incompatibility with the prayer order. This is what Rabbi Chaim Navon brought up in his article “The Prayer Form in a Changing Reality” under the name of Yeshil Abdi. I do not know if he rules this in practice (unfortunately, the relevant part – Ch. H., the omissions, cf. 4 – is not found in the Shulchan project).
In addition, even if this is permitted, the question arises as to whether it is possible for an individual to act in this way or whether it is something that the public should lead (especially when it comes to public needs, it is not clear whether the individual can decide this).
What does the Rabbi think, is this forbidden/permitted/recommended?
