Hi,
You can use corresponding general space feng shui activations with your personal energy number activations yet the time feng shui activations are pretty specific. For example, say you want to support a loving relationship in your life and we'll pretend your personal relationship direction is the SE. You can place your activation card in the SE along with items that represent what you want for that relationship.You can also utilize the general colors or elements of the SE to enhance that area as well.
Regarding the hexagram, Marie mentions in the Hexagrams course that a beneficial hexagram for relationship is 20.4. I do suggest calling in a speaking to one of the coaches in person. It sounds like you may have a very specific goal to take care of.
All the best!
