You can. There are two approaches. One is to use "verbatim" keyword that Tyson pointed you to. The other one is to use loose ERO.
When you create a tunnel path, on a head-end router, you provide all the exact hops to the "ABR" (I will use that term loosely here). When you specify the next hop, it needs to be the tail-end of the tunnel specified as "loose". The reason for that is that head-end router doesn't have the information about the other area. The decision about the exact path is left to the ABR and it will use its own database to calculate the best path to the tail-end. Here is the example: R1--R2--R3--R4--R5--R6 R1 through R3 are area A and R3 through R6 are area B. ip explicit-path name R1-to-R6 next-hop address-of-R2 next-hop address-of-R3 next-hop loose address-of-R6 !
