Same file in multiple changelists in perforce

Question

Is there any way to have the same file be a part of multiples changelists in perforce? With that I mean that from the set of changed lines in the file one subset will belong

Answer 1

Bonus answer: I found this feature in Rational Team Concert (http://www-03.ibm.com/software/products/en/rtc/). You can have the same file in many changesets. If you want to add File1 to Changeset1 and Changeset2, you must complete Changeset1 first. This allows you to add File 2 to Changeset2 but then a dependency between changesets is created, so you can not deliver Changeset2 without delivering Changeset1 too. Moreover you can not make changes to a complete changeset.
