[REQ] Selective Operation/Tag Generation with automatic schema inference

[asafbennatan]

Is your feature request related to a problem? Please describe.

i have a large spec file with alot of apis (jira spec) , i would like to generate only one (or few) specific operations/tags
and their relevant schemas

for example lets say i want to generate only searchProjects operation so it will generate the searchProjects api with #/components/schemas/PageBeanProject schema and all dependent schema (used properties schemas , inheritance etc)

i believe this is quite common use case , specs are usually sent as one single file which can be quite huge

Describe the solution you'd like

i want to input operation ids or tags and generate only these apis and their schemas

Describe alternatives you've considered

i read that i can use FILTER=operationId:searchProjects
but this still generates unrelated schema

i assume i could select the apis and the related nested schemas required for these apis but this is very tedious to do for nested models
