I am using the spalign package to typeset matrices and systems of equations.

Basically it just lets you use spaces (or commas) and semicolons instead of & and \ when typing in matrices and similar things based on arrays.

I would like to vertically align some matrices or systems of equations as though their baseline is the baseline of the first row (or equation) rather than being vertically centered, as can be done in the array environment by using the [t] option.

MWE is:

documentclass[12pt]report
usepackagespalign
usepackageamsmath

begindocument
Normal matrix vertically aligned so that it is vertically centered:

[
 A=spalignmat1 2 3;4 5 6;7 8 9
]

The same matrix using amsmath environments:
[
 A=beginpmatrix
 1&2&3\
 4&5&6\
 7&8&9
 endpmatrix
]

I would like it to vertically align with baseline at the baseline of the first row, like you can do with an array:

[
 A=beginarray[t]ccc
 1&2&3\
 4&5&6\
 7&8&9
 endarray
]

A system using spalign:
$spalignsys2x + 3y = 1;x - y = 10$
enddocument

I would like to be able to align the matrix (and system) the way the array is aligned. The spalign package has tools to create your own shortcut commands (so I know how to make a top-aligned array environment that uses the spalign shortcuts), but I don't know how to make it automatically handle the delimiters and column alignments. Similarly, I can use array environment to typeset the system, but it's nice to have the number of variables and such handled automatically as in spalign.

If it can't be done in spalign, a solution using the pmatrix environment would be the next best thing (however, as you can see in the example, the spacing between the array and delimiters is a little different there, so it's not ideal for me, since it would look different than my other matrices).

Thanks for any help!
