Welcome to the community, thanks for reaching out.
It is not possible to connect your SoundLink portable speakers to your SoundTouch products in a group as the SoundLink products are not compatible with the SoundTouch app. I apologize for any disappointment this causes.
Something I could suggest is an AUX wired connection between the SoundLink Revolve and the SoundTouch Wave IV, however this may not be practical considering your 10m distancing.
Please let us know if you have any further questions.
