There are two ways you can read the 'please cite as'
- As a helpful guide
You can read this 'please cite as advice' literally and try to cite sources exactly as specified there. But that can quickly lead to highly inconsistent bibliographies if you obtain the 'please cite's from different sources.
Just imagine a case where one 'please cite as' gives names in the format 'Anne Uthor', another in 'A. Uthor' and a third one as 'Uthor, A.'. Imagine further that one advice says to place the year after the authors and another one places it at the end. The advices may very well differ in the way they format titles and volume numbers of journals.

I have never seen a citation style guide that has not in some way pointed out the importance of consistency in the bibliography. You would be prone to have to give up consistency immediately if a different 'please cite as' comes along.
biblatex and Biber (and BibTeX) were made to enable you to have a consistent bibliography that allows for changes in styles, you will find that they are probably not the right tool if you want to take the literal approach to honouring 'please cite as'. You could theoretically use them to manage your bibliography. That would involve formatting the output as in the 'please cite as' yourself (in a single field
bibdata, say) and creating a new
biblatex style that prints only the
bibdata field. This only gives the slight advantage over a manual
thebibliography that you can use BIber/BibTeX for sorting (you probably need to use a special field to indicate sort-order) and to retrieve only the works cited from a file. (My answer to How to set up BibLaTeX for use with 'freeform' citations shows roughly how that could work.)
I suggest, however, that you take the 'please cite as' advice not literally, but rather as guidance of what information your bibliography should contain when you cite this particular reference. You are free to arrange the info in a way you see fit (or the style you have to follow dictates), but you are not bound to the exact output of the 'please cite as' example. That then allows you to use
biblatex as usual.
