Can I apply for FY2 even when I filled CREST form?

Hi I am a little confused about this. I have been applying to FY2 jobs since 6 months now with no interview in sight. However I am not discouraged. I decided to get my crest signed and apply for MSRA to directly enter training.

However I would still want to keep applying for FY2 jobs to get experience before I enter training. Is it possible to do that or you cannot enter FY2 if crest is done
