Startswith in Crystal

Hi there,
I'd like to consolidate my coding and currently have:

or Not Isnull ({CnGf_1AttrCat_1.CnGf_1AttrCat_1_Import_ID})
and {CnGf_1AttrCat_1.CnGf_1AttrCat_1_Comments} startswith "K12-"
or Not Isnull ({CnGf_1AttrCat_1.CnGf_1AttrCat_1_Import_ID})
and {CnGf_1AttrCat_1.CnGf_1AttrCat_1_Comments} startswith "K17-"
or Not Isnull ({CnGf_1AttrCat_1.CnGf_1AttrCat_1_Import_ID})
and {CnGf_1AttrCat_1.CnGf_1AttrCat_1_Comments} startswith "K18-"

Is there are something similar to the "in" function that will allow me to say
Not Isnull ({CnGf_1AttrCat_1.CnGf_1AttrCat_1_Import_ID})
and {CnGf_1AttrCat_1.CnGf_1AttrCat_1_Comments} in (startswith ["K12-" , "K17", "K18"]) just to consolidate it to make it easier for future reference?

Thanks in advance,
CS
