Can I use a IFFT HDL Optimized block with an input length greater than 2^16?

I have an input data greater than 2^16 and i wanted to know if there's a way to use the block IFFT HDL Opltimized for it. Maybe putting more blocks in parallel, but will the result be the same?

FFT length — Number of data points used for one FFT calculation

1024 (default)

This parameter specifies the number of data points used for one inverse-fast-fourier-transform (IFFT) calculation. For HDL code generation, the FFT length must be a power of 2 between 23 and 216.
