Just get the Sec / Chairperson to tell the SM to transfer the funds (remember the SM works for you (the owners) and has to comply with your wishes). If they object you might have to pass a motion by the EC instructing the SM to do this.
Sometimes it’s a bit of a grey area where the money comes from but ultimately it is the EC or OC that makes the decision (under advisement from the SM) not the SM themselves.
