how to count the total newly created bond of the certain type?

hello everyone,
Have anyone has an idea about computing the total newly created bond number of the certain type during simulation?
I imagine to use "compute property/local" "variable "to form a group and then "count()" the number.
However,the "compute property/local " command can only return a local type value which can not be used by "variable atom".
So,how can i realize it in lammps during simulation?

What is a newly created bond, and how are you creating it?

If it’s via a fix, then the fix probably tallies the count (e.g. fix bond/create).

The compute reduce command can sum “local” values produced
by another compute.
