set band metadata

is it supported/foreseen to set band level metadata using gdalraster? ``` library(gdalraster) ds <- new(GDALRaster, "test.tif", update=TRUE) band <- ds$getRasterBand(1) band$setDescription("Band 1 name") ds$close() ``` currently: ``` Error in envRefInferField(x, what, getClass(class(x)), selfEnv) : 'getRasterBand' is not a valid field or method name for reference class "Rcpp_GDALRaster" ```
