Kodak does indeed have some magic in encapsulating the

Dektol as single packages. However, in the past both came as double

Metol does not dissolve well in sodium sulfite solution so it
should be put up separately. AFAIK, the other ingredients can be
combined.
Ansco used to sell packaged 47 so its doable.
BTW, Ansco/Agfa 47 appears to be essentially identical to Kodak
D-61a except for strength. The ingredients of the Kodak formula are
double those of the Ansco formula.
Thank you Richard. I can easily keep the Metol separate. I don't
know where I originally came up with the Ansco 47 formula, I have
used it for many years for negs to be platinum printed. It gives a
sparkling clean white. It is better for me to pre package dry
chemicals than try to bottle concentrates.
