This is not "a simple click", but the following python code works for me:

#get the proxy to your object, example

pm = servermanager.ProxyManager()
slice = pm.GetProxy('sources', 'Slice1')

#get the data range

range =
slice.GetDataInformation().GetPointDataInformation().GetArrayInformation(0).GetComponentRange(0)

# find a proxy to the representation of your object
# iterate until you find the right one, e.g.

print pm.GetProxiesInGroup("representations")
#  once you know your proxy, e.g.

rep = pm.GetProxy("representations", "DataRepresentation4")

# get its lookuptable and the RGBpoints array

table = rep.LookupTable.GetData().RGBPoints
# you can now set it to your data range

table[0] = range[0]
table[4] = range[1]



Your mileage will vary. Error checking is left as an exercise
