Loading data on external EEPROM with Pickit4

Hello, 
I have a question about a functionality of PICkit4. Is it possible to loading data on SPI external EEPROM ?
I don't find any information, I just know it's possible with PICkit3 but I don't know if it's possible with PICkit4.
 
Thank you for your answers.
Arnaud

No,  EEPROMs are not supported by PICKit 4

Is the SPI EEPROM connected to a PIC?
 
You could embed it in the program FLASH of a simple project to write it to the external EEPROM. Deoends which PIC and how much data, of course. You might even be able to compress it and uncompress it before writing.

Yes the SPI EEPROM is connected to a PIC but the memory is too small to write the external EEPROM. 
But I think that I am going to make  a "bootloader" to write EEPROM with USB and PIC.

What PIC?
The more information you provide, the more help we can offer.
Does this PIC have any communication with the outside world? e.g. a serial port?

It's a PIC16F15325 and the memory is a 25LC1024. 
This PIC have a UART, SPI and I2C. So I think with a USB/UART converter I can loading data on EEPROM, what do you think?

Indeed. That's exactly how I do it in a simple project with a small PIC16 device and a large FLASH chip.
I just have some pads on 0.1" centres with Gnd/Tx/Rx from the PIC, and talk to it with a TTL USB/serial adaptor.
