[BioC] Expressionset from ArrayExpress processed data

Dear BioC users,

I'm working with experiments from the ArrayExpress database and some of them do not provide the cell files, but instead the already processed data in a table fromat (esasy to read with read.delim, for instance). The PhenoData of the experiment comes separately in the sdrf file. Is there a way to create an expressionset object from these two?
The ArrayExpress package only provides functions for creating an AffyBatch object from the raw data and the sdrf, adf and idf files; but has nothing so far to deal with the processed data.

Thanks so much,
