Jan Stránský proposed the following answer:
Hello Henry,

I personally don't know about any implemented function for your situation.
However, you can write your own python code :-) something like:

class AccelerogramApplier:
  def __init__(self,bodies,accelerogram):
     self.accelerogram = accelerogram
     self.bodies = bodies
  def getAccel(self):

for t,a in self.acceleration:
        if O.time > t: break

  def applyAccel(self):
     a = self.getAceleration()
     for b in self.bodies:
        O.forces.addF(b.id,a*b.state.mass)
accelerogram = [(0.0,0.0),(0.4,2.0),(0.8,3.2),(1.2,0.9),(1.6,-0.4),...] #
time-acceleration pairs, the format may be any other , possibly loaded from
file
