Syntax Search Help

I just found something that I don't remember seeing in the past. In 2 Thessalonians 1:4 we read:

ὥστε αὐτοὺς ἡμᾶς ἐν ὑμῖν ἐγκαυχᾶσθαι ἐν ταῖς ἐκκλησίαις τοῦ θεοῦ

The LSB renders this as:

so that we ourselves boast about you among the churches of God.

The two accusative personal pronouns grabbed my attention. This is what Bill Mounce (Basics of Biblical Greek, chapter 12) calls the "Adjectival Usage" of the personal pronoun αὐτός. Mounce's text says:

"§12.11 When functioning as an intensive, αὐτός is usually in the nominative case and modifies the subject."

What is happening here is that the intensive form of the pronoun αὐτός is found in the accusative case, but it is modifying the accusative subject of the infinitive ἐγκαυχᾶσθαι.

I wanted to form some kind of a syntax search to find other instances where this use might be found in a case other than the nominative. I went to Cascadia Syntax Graphs, where this pronoun is identified as "pronoun, personal, third person, accusative, plural, masculine, intensive predicative."

How could I search the NT for all the instances of the "intensive predicative" pronouns? I appreciate any help you can give me.
