Watershed without repeating flow accumulation?

I frequently create models to delineate and export stream rasters from DEM input.  However, on large basins, computing basin accumulation (thanks to ESRI, on just one core) takes hours and has to be done twice, once for the accumulation step and once again in the watershed command.  The latter neither uses the already present accumulation nor does it save it such that I wouldn't have to compute it separately.  Any way around this?

And to the watershed command, let me add stream link, basin and stream link.  Each recalculates flow accumulation and doesn't save it.  For clarity, I am using ArcGIS Pro 2.0 in model builder.
