Multiple IntRects in a single Sprite

I'm trying to do level gen but I want to have a single sprite for the level. I have a sprite sheet and i would like to assign different textures to different "areas" of a sprite.
sprite.
setTextureRect
(
sf
::
IntRect
(
0
,
0
,
32
,
32
)
)
;
sprite.
setTextureRect
(
sf
::
IntRect
(
32
,
32
,
32
,
32
)
)
;
The code above I know would replace the texture rect but is there a way that I can have both?

A sprite is a single area of a texture but there are ways to draw multiple areas at once.
The first - and probably easiest - way is to just have multiple sprites with one for each area of the texture.
The second is more powerful but a bit more complex: vertex array.
The idea here is that each quad can have its own area of a texture. With a vertex array, you can have multiple quads as one object (a single draw call and all transformations apply to all quads together).
Take a look at the
vertex array tutorial
to see how it works.
Specifically, take extra note of
the tile map example part
.

Yes, what Hapax said.
However if for some weird reason you want to draw everything with the same sprite, you can set the texture rect, draw, set a different texture rect, draw, etc.
