Ok, lets see.....
Not really clear on what you're saying, simply because I don't have my mind around the dominants and secondary dominants. I'm playing by the chord progressions. Let me give you an example of where I am:
1 - Major, Madd9
2 - Minor, m7
3 - minor, augmented
4 - major, M7, Madd9
5 - Major, M7
6 - Minor
7 - Dim, or 1/2 dim
As of this week I starting to incorporate 9ths. So regardless of the progression, thats the chords I'm thinking when I play those tones. As you can see, I'm still learning, but I give thanks to God for this website and your knowledge, bruh. Anyway, thats where I am. Any advice would be greatly appreciated
