How to use Twinmotion for stage design. How to create a lighting fixtures and beams

I adore TM and I work as a stage designer. but I only discovered one choice for my purposes.
One way to construct a stage is to use Sketchup to draw a whole stage with lighting equipment, such as static fixtures, and then manually place the beams using the spotlight component.
The first issue is that the hazy beams from the spotlight at tiny angles appear extremely dirty and pixelated when rendered in real time.
2. I’m unable to get them to move or change color for the video.
3. It is quite difficult to replace a light manually if I have more than 100 fixtures.

Does anyone know of any alternative solutions?
Is it possible to program my own smart asset with all of these parameters?
