Parameterize the number of iterations in the Gremlin pageRank step

As far as I understand gremlin pageRank step (g.V().pageRank()) runs a PageRank vertex program with 30 iterations.

Is it possible to change the max number of iterations?

This should work:

g.V().pageRank().times(5)

There's an example of this in the Apache TinkerPop docs:

gremlin> g.V().pageRank().by('pageRank').times(5).order().by('pageRank').valueMap()
==>[pageRank:[0.15000000000000002],name:[marko],age:[29]]
==>[pageRank:[0.15000000000000002],name:[peter],age:[35]]
==>[pageRank:[0.19250000000000003],name:[vadas],age:[27]]
==>[pageRank:[0.19250000000000003],name:[josh],age:[32]]
==>[pageRank:[0.23181250000000003],name:[ripple],lang:[java]]
==>[pageRank:[0.4018125],name:[lop],lang:[java]]
